Applying the distance formula, the Fatimas error is: B.The side measures 7 units, not 9 units.

What is the Distance Formula?

  • Distance formula is used to calculate the distance between two points on a line segment on a coordinate plane.
  • Distance formula is given as, [tex]d = \sqrt{(y_2 - y_1)^2 + (x_2 - x_1)^2}[/tex].

Find the distance between (-8,1) and (-8,8):

[tex]d = \sqrt{(8 - 1)^2 + (-8 -(-8))^2}\\\\d = \sqrt{49} \\\mathbf{d = 7 units}[/tex]

Therefore, applying the distance formula, the Fatimas error is: B.The side measures 7 units, not 9 units.
